My friend Ed Crowne came up to me as I was making my work rounds. At the east end of Center drive a robust cheery singing PROTHONOTARY WARBLER was music to Ed's ears. The bird stayed put along that stretch most of the morning.
Two BLACK VULTURES flew over Prospect Lake.
At Terrace Bridge at peak time for empidonax flycatchers an ALDER FLYCATCHER kept it up with its calling. It's important to know the call notes to distinguish the four eastern empids.
In the Midwood, a likely BICKNELLS THRUSH almost identical to Gray Cheeked thrush before the species was split by the AOU usually give itself away with its chip song.
And since we are in the breeding season both SCARLET TANAGER and INDIGO BUNTING were observed carrying nesting material at Butterfly Meadow. It's reassuring to know my spark boid tanager wants to settle down here.
Enjoy your holiday weekend.
